In this study, the effect of glycerol concentrations (60, 70 and 80 %) and drying temperatures (45, 60 and 75 °C) on physical and mechanical properties of Lepidium perfoliatum seed gum-grass pea (Lathyrus sativus) protein isolate composite film was investigated. Results showed that with increasing the temperature from 45°C to 75°C, the drying time needed for the composite film containing 60 and 70% reduced. Whilst, drying times of the samples with 70 and 80% glycerol were nearly the same. Water solubility, moisture absorption and elongation at break (E%) reduced when the drying temperature increased and the elastic modulus (EM) decreased. With increasing glycerol concentration from 60 to 80 %, water solubility and moisture absorption increased and E% and EM reduced.
